Abrupt temperature change is best when attempting to kill bed bugs, so the bugs do not have time to adjust to the new temperature. Because it can take many hours for heat or cold to penetrate objects, the process of killing bed bugs is complicated by the density and depth of the items to be heated or frozen. It may take 15 days at 32 F to kill bed bug adults and 30 days to kill bed bug eggs that are unprotected, and much longer to kill those that are hidden inside items. Temperatures below freezing will kill quicker, but less is known about killing bed bugs with cold compared with using heat against them.
"In the past, bedbugs have repeatedly shown the ability to develop resistance to products overly relied upon for their control. The findings of the current study also show similar trends in regard to chlorfenapyr and bifenthrin resistance development in bedbugs," study researcher Ameya Gondhalekar, research assistant professor at Purdue's Center for Urban and Industrial Pest Management, said in the Entomology Today statement. "With these findings in mind and from an insecticide resistance management perspective, both bifenthrin and chlorfenapyr should be integrated with other methods used for bed bug elimination in order to preserve their efficacy in the long term."

Caregivers, firefighters, and other service providers are sometimes required to enter and work in bed bug-infested dwellings. In doing so, there is the potential to transport some bugs home or to the workplace. It should be noted that bed bugs do not fly, nor jump onto people/pets as fleas do. During the day, bed bugs usually remain hidden and immobile, becoming more active at night when seeking a host. Consequently, the chance of picking up bed bugs by merely walking into an infested dwelling during the day is unlikely. The risk may increase while providing care but can be lessened by taking some precautions.
Next, vacuum and steam along baseboards, window sills, and the edge of the carpet. When you’re done vacuuming, the bag or canister should be cleaned or discarded to limit exposure of bed bugs to other parts of the home. The steamer can also be used to treat sofas, chairs, furniture, and cabinets. When applying steam, remember to move the nozzle slowly (about one inch per second) to ensure that all bed bugs and eggs are killed.
To get rid of bed bugs in a mattress, use an aerosol spray labeled for bed bug treatment, such as Bedlam Aerosol Spray, and spray or mist the insecticide onto the mattress. Focus on the seams, tufts, and folds of the mattress and spray until the mattress is damp. Allow mattress to dry before remaking the bed with freshly laundered sheets that have been run through a dryer on high heat.
Our place is pretty cluttered so I was freaking out. Luckily we have hardwood floors and not carpet. We tried different things. It gets really hot here, so I loaded up any nearby sheets, pillows, comforters, clothes, etc into trash bags and tied them off so nothing could get out. I put those in the car so the sun could beat heat into them all day. Never thought I’d be so thankful for Texas summers… Still got bites. We bought a mattress cover. Still got bites. We thought, okay, maybe they’re coming from the wall socket from a neighbors or something. We couldn’t close it so we kept the bed away from furniture and walls and put sticky traps on the legs. Caught NO bed bugs but STILL GOT BITES. I was losing my mind.
Great read and very helpful info. However, when you describe how to use essential oil sprays for bed bug treatment, it would be most helpful if you included the amount of water used to mix with the oils. Simply stating to use “a small spray bottle filled with water” isn’t a very good description. A quick search for “small spray bottle” will get results for a wide range from 2-ml to 16-ounce bottles, all classified as small. This makes for a rather potent mixture to an extremely weak mixture.
Bedbug bites may go unnoticed or be mistaken for flea or mosquito bites or other types of rash or skin conditions, since the signs of bedbug bites are difficult to distinguish from other bites or skin conditions. Bedbugs also have glands whose secretions may leave musty odors, and they also may leave dark fecal spots on bed sheets and around places where they hide (in crevices or protected areas around the bed or anywhere in the room).
Visit your doctor. You can also see a doctor for diagnosis if you do not find signs of bedbugs in your bed and cannot identify the source of the bites or rash. However, there is a very good chance that your physician will not be able to firmly diagnose that you have been bitten by a bedbug because the symptoms look so similar to those that result from other insect bites and skin conditions. Nevertheless, you may feel comforted by going to see your doctor, who can confirm for you that bedbugs pose little physical threat to humans.
Mix 3 oz per gallon or 0.75 oz per quart and spray with a low pressure sprayer into the areas where the bed bugs are hiding. Typical areas include bed frames, headboards, under beds, baseboards, moldings, behind pictures,etc. Remember to apply in the joints and crevices of furniture. If the crack and crevice is too small, use an aerosol with a crack and crevice tip (recommendations are below.)
With the bed now fully isolated and elevated, bed bugs hiding elsewhere in the room won’t be able to feed on you or hide in your bed. You can also use the ClimbUps to monitor the changing population of bed bugs in your home. Hopefully, you will see less and less bugs appear in the traps as you go through the next steps. Now that you have created a safe haven in your bed, you can move on to treating the rest of the room.
